how much HP can i expect to gain if i add this to my 99 sentra GXE 1.6L

 

before you buy that injen cold air intake i would recommend you get a hot shot performance cold air intake. cause i put the hot shot cold air intake on my 97 sentra w/ 1.6 and i picked up more hp then i did with my injen that i had on it before. but the hot shot cai give more hp then any other cai on the market for the 1.6L you should see about 9hp gain with the hot shot you will mostly notice it in your mid to top end power.

 

I have the place racing on mine and am more than happy with that.

 

I have a Injen on my SE-R, i must say its nice... but the pipe diameter goes from a 2.5 down to a 3 inch. The fitment is nice, but im not digging the chrome it came in thinking about going place racing for only 120$ my Injen was almost 300!
